Definitely does the job

It is kind of difficult to review an app based on what you do not see. That being said, this app certainly blocks almost all of advertising that I have potentially encountered. If it has let any advertising through, it is not been anything I have noticed. That is why I rate it only 4 stars, because I cannot confirm results from the app. I certainly recommend it, but I have reservations about not being able to determine the specifics of its operation. I also would like clarity as to whether or not the app uses logging in its operation. More transparency please.
